RICHARD Bf CARRAN, OF LUDLOV, KENTUCKY.

HINGE.

SPECIFICATION forming part of Letters Patent No. 346,264, dated July 27, 1886.

Application filed November 12, 1885.

To all whom, it may concern:

Be it known that I, Iticrraizn B. CARRAN, of the city of Ludlow, county of Kenton, State of Kentucky, have invented a new and useful Improvement in Hinges, which is fully set forth in the following specilication, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to that class of hinges that are self-closing.

rThe object of my invention is to provide a self-closing hinge which is simple in construction, has few working parts, easily applied, durable in its action, and with less liability to become disordered from rusting of the work- 4 ing parts.

Figure l is a side elevation of a hinge embodying my invention. Fig. 2 is a plan view of the sanie. Fig. 3 is a detail view. Fig. 4 shows a modification.

My invention consists in the construction and combination of parts hereinafter described and claimed, reference being made to the accompanying drawings.

B is the stationary part, or that part which is fastened to the gate or door post. It consists 0f a iiange or face-plate, B, having a circular shelf or projection extending to the front of the face-plate about three-fourths of its di aineter. On the upper edge it is beveled off toward its periphery and forms a beveled spiralincline similar to the segment of one thread ofascrew. This projection is made on the faceplate at an angle of about twenty-live degrees from a horizontal line across the face. The pin or pintle C is made in the center of the circle of the shelf or projection in a vertical line, and a bracket, b, is placed directly under the pintle, for the purpose of giving strength and support to the projection. Screw-holesf are made in the face-plate or fiange B, for the purpose of attaching the hinge to the gate or door post.

D is the beveled incline, (the pitch or in ward inclination of which is upward and central toward the center of the pin C) which pin C forms the pivot around which the roller and niovable'part ofthe hinge travel.

E represents a beveled friction wheel or roller, the pitch or periphery of which corresponds with that of the beveled spiral incline D, on the upper surface of which it rolls when Serial No. 182,626. (No model.)

the part A is swung to and fro, thereby giving an upward and downward motion to the part A when in position, as shown in Fig. 1. (The beveled incline travels upon the roller when iu position as shown in Fig. 4.) The axle ol" the beveled roller is on a line horizontally at a right angle with the center line ofthe pin or pintle C.

c is the casing or hood that ineloses the roller E and supports the axle e of said roller E.

bis a circular or spiral groove or depression, for the purpose ot' carrying off the water from rain &e. ,which flows off at the lowest point, b2.

In order to protect the roller E in the casing e from dirt and any foreign substances getting in, to interfere with the operation of the beveled roller E, I provide a guard or rim, B', that overhangs the beveled spiral incline D, which prevents the insertion ofsubstances that would obstruct the beveled roller E. In this position of the hinge the relation ofthe roller to the beveled spiral incline is the same asin Fig. 1, except that the beveled spiral incline travels upon the roller.

My invention may be applied to gates, doors, shutters, blinds, Src., when the object is to have them self-closing, and it is clearly to be seen that where a door or gate is hinged with this device the opening of the gateor door causes the part A to rise by means of the beveled roller E ascending the beveled spiral ineline D, and when the door or gate is rcleased it descends by gravitation and closes.

I am aware that inclines and rollers have been used in the manufacture of hinges, and also that a beveled incline and beveled roller are used; but in these eases the construction is quite different from that in which I make my hinge.

In my hinge the beveled incline and the beveled roller are made with the periphery of 'the roller E to exactly correspond and match that of the spiral incline, andthe axle of the roller is at right angle with the center line of the pin or pintle C, and also the angle of these bevels is the saine as would be required to make a beveled gear (pinion and wheel) of the same relative proportions to operate at right angles to each other, the beveled roller representing the pinion resting on or traveling upon the wheel, the wheel being represented by the spiral incline in my hinge. rllhis part IOO of the hinge is made in one casting. The .angle or inclination of the bevel of the spiral incline being less than forty-five degrees, there is but little tendency to slip doWn or sag with the Weight of the gate or door, and conse quently little frictional contact upon the ,pin- The swinging-arm" tle C with the eye A'. movable part of the hinge A is made with an eye, A', to fit the pintle C. On one side of this eye A' is the extension in'which the casing or hoodeis formed, said casing or hood extending forward of the front line of Athis part of the extension a sufiicient distance t0 permit lthe insertion of the pin e', which forms the axle of the beveled roller, through from one side to the other of the casingfor hood, and fastening it by riveting or yother- Wise. Then this extension or arm diverges from this straight line backward to a line Veven with the rear lineof the lface-plate,

l and then it takes the line parallel to that on which it 'starts from the eye A', as shown inv Figs. 2 and 3. It is then provided with lugs-or fasteningit to-the gate or door.

extensions g', in which are screw-holes for The rearline of the face-plateB" and the rear surfaces of the flanges or projections g g' g being on a line gives great facility for applying the hinge, i

as it is screwed to the front face of both gate and'post.

Having ,thus fully described my invention,

what I claim as new, and for which I desire Y Letters Patent, is-

The combination of the face-plate having the incline D, bracket b, and pintle c, formed as a part thereof, with the swinging arm A,

having an eye, A', formed at its inner end to catch over the pintle, and a casing, e, the beveled roller E, and journal e', substantially as `shown and described.
